>From the manual:



> NOPASSWD and PASSWD

> 

> By default, sudo requires that a user authenticate him or

> NOPASSWD tag.  Like a Runas_Spec, the NOPASSWD tag sets a

> PASSWD tag can be used to reverse things.  For example:

> 

> ray    rushmore = NOPASSWD: /bin/kill, /bin/ls, /usr/bin/lprm

> 

> would allow the user ray to run /bin/kill, /bin/ls, and
> /usr/bin/lprm

> as root on the machine rushmore as root without authenticating
> himself.

> 

> ray    rushmore = NOPASSWD: /bin/kill, PASSWD: /bin/ls,
> /usr/bin/lprm

> Note, however, that the PASSWD tag has no effect on users who
